Cyclic vomiting syndrome (CVS) involves recurrent, self-limited episodes of nausea and vomiting. These episodes, often triggered by stress or infections, can persist for years without a predictable end.

Area of Science:

  • Pediatrics
  • Gastroenterology
  • Neurology

Background:

  • Cyclic vomiting syndrome (CVS) is characterized by recurrent, discrete episodes of intense nausea and vomiting.
  • These episodes are typically self-limited, lasting hours to days, and are separated by symptom-free intervals.
  • CVS is a functional disorder, meaning it is not caused by an identifiable underlying organic disease.

Purpose of the Study:

  • To describe the clinical characteristics and natural history of cyclic vomiting syndrome.
  • To identify common triggers and age of onset for CVS.
  • To highlight the chronic and unpredictable nature of CVS episodes.

Main Methods:

  • This abstract describes a condition based on established clinical definitions and observations.

  • Data on episode characteristics, triggers, age of onset, and duration were compiled.
  • The study focuses on the phenomenology of CVS in affected individuals.

    • Main Results:

    • CVS episodes are similar in onset, duration, and symptoms for each patient.
    • Common triggers include heightened emotional states and infections.
    • Onset typically occurs in early childhood, but can begin at any age.
    • Episodes can recur for months or decades with unpredictable subsidence.

    Conclusions:

    • Cyclic vomiting syndrome is a distinct disorder with characteristic episodic vomiting.
    • Emotional stress and infections are frequent precipitating factors.
    • The chronic and often prolonged course of CVS necessitates ongoing management and support.
